To aZZ whom t may concern:

Beit known that I, JACK IMBER, a sub- Jject of the King of Great Britain and I reland, and residing at 162 Worple road, Wimbledon, London, S. W. 19, England, have invented certain new and useful Improvements in Tanks or Receptacles for Combustible or other Liquids, of which the following is a specification.

This inventionrelates to tanks or receptacles for combustible or other liquids and is more particularly intended for petrol or other combustible liquid tanks carried upon aircraft or other vehicles or exposed in other situations wherethey are liable to be pierced by incendiary or other projectiles'.

The object of the present'invention is to so improve the construction of such tanks as to prevent or minimize the leakage of liquid in the event of the tank being pierced and to prevent the contents from taking fire should the projectile be of an incensweated or welded or otherwise formed without the necessity for the employment of rivets or other` parts passing through the shell or casing.

. The invention also consists in a tank or receptacle of the above character in which the inlet, outlet and other fittings are sweated or welded to the tank and provided with at least two seatings so that in the event of one being destroyed the other will operate to prevent leakage.

The invention also comprises the form ofy tank or receptacle hereinafter larly described.

The accompanying drawings illustrate one more particuform of tank in accordance with lthe inventionz` c c ,y

Figure l is a side'felevation, 'half in section;v

Fig, 3 is a plan, half in section gf 4^ Fig. 4 isa section on a-larger scale of a fitting; l

Fig. 5 is a perspective view of they inner cradle, while Fig. 6 is a detail section ythrough the joint between the edges of the surrounding shell, Fig. 7 is an enlarged elevation of the partition attachment,

tition, in advance of the attaching strip,

Fig.v 9 'is a detail section showing the means for connecting onel end or bottom and the shell, and f f ig. 10 is a detail section through one partition.

In carrying vmy inventioninto effect in the manner illustrated when forming, for example, a petrol tank for use upon aircraft, I construct the inner cradle or framework preferably of tubular or other light but strong construction, the cradle being formed from outer peripheral members a conforming to the shape of the finished tank and cross members or struts b, the various members being sweated or welded to one another to form a complete cradle (shown more clearly in Fig. 5) which will fit within and conform to the shape of the outer shell or casing c. kThe latter is wrapped around to give its finished shape and the joint is sweated or welded or otherwise formed (as shown, for example, at d in Fig. 6), without the necessity for the employment of rivets or other members passing'through the material and one end ofJ the outerv casing is then placed in position Aand fianged over and welded or sweated tothe casing proper. The cradle or framework maythenvbe slid into position in the tank and the other end put on a manner similar to that above described or, if desired, the tank may' be formed a Situ aroundy oruponthe cradle v or framework. The outer'or end peripheral members a are provided withtubular rods or elements a, which cross 'andare secured to said members, These.' rods serve to reinforce and.A stiffen the end members and the ends offthe'receptacle. y'

internal lbaos lor partitionsv such c j Y c 'K as '9,1 arefto-,jbe lprovided iny the tank, these Fig. 2 is an end elevation, halfinsection m'ayonmay not be perforated 'as shown at Lf e, ."and"ma'y be secured to the'framework by bel'ngriveted or otherwise secured to clips Fig. 8 is a detail section through the parf (shown more clearly in Figs. 7 and 8) upn the members of the-framework or in il any other suitable manner so that the cradle and baiies may thus form an integral whole within the outer shell or casing c. The partitions obviously serve to limit the iiow of the gasolene or other iuid in any one direction incident to change in positions of the tank, that is such low is temporarily fbaflied, and the fluid maintained in a more normall condition. The latter is then covered upon its exterior by means of a suitable covering g of rubber or like material,

the best composition at presentl known to me for the purpose consisting of 91 per cent. hard Para rubber, 7 per cent, sulfur and 2 per cent. of magnesia, the covering being vulcanized for, say, 75 minutes under a steam pressure of about lbs. per square inch.

It is to be understood that any suitable rubber or like composition may be substituted for that referred to above, and also I may form the cover from a plurality of superposed sheets of any desired thickness.

If necessary or desirable, the corners may be reinforced byf/an additional rubber covering h. rIhe construction is such that the tank or receptacle will be of comparatively light but very' rigid construction and the inner cradle or framework will form a backing against which the rubber covering may seat itself to form a self-sealing covering in the event of the metal shell c of the tank being pierced and will thus prevent leakage of the liquid contents of the tank while at the same time the resilient or elastic covering will return to its seating against the cradle or framework in such a brier` space of time that it will be impossible for the contents to ignite in the event of the projectile being of an incendiary character.

In order to provide for the greater security of the tank o-r receptacle against leakage, all fittings thereon are provided with double seatings so that in the event of one f joint giving way there will still be a second joint to prevent leakage. Y

In one convenient construction illustrated in detail in Fig. 4 in connection with one form of fitting, this may be effected, for example, b having a flanged internally threaded ush z' sweated upon the inside of the casing c and surrounding the aperture for the fitting, and into this I screw a second bush or sleeve 1c which carries the fitting and which makes with the first-mentioned member a 'oint by means of fiber or other packing. his second bush or sleeve pro-A jects beyond the rubber or like covering of the tank and is surrounded by a metal washer l which may or may .not be corrugated and is forced into close contact with the exterior ofvsuch covering or with an additional rubber washer m by means of a ring nut or the like screwed upon the outer end of the bush or sleeve, or by means of a second joint or seating for the fitting.

If desired, the bush i may be so constructed and arranged that it is substantially ush with the inner surface of the metal shell.

The exact arrangement of,l parts in con nection with the fitting may be suitably modified depending upon the character of the fitting concerned as, for example, the washer may be dispensed with and its place taken by a flange upon the ring nut or the like which isthreaded upon the outside of the bush or sleeve. In some cases it may be found necessary .to employ rivets or the like when forming the joint in the outer shell or casing, but it is preferred, whenever possible, to avoid their use altogether.

It is to be understood that the invention is not to beconined to the foregoing application given by-w'ay of example only, nor to the particular details of construction described, as the invention is applicable to any particular form of tank or receptacle whether of circular, elliptical, rectangular or other form in cross-section and whether having plain or convex or other shaped ends or sides, and I modify the form and construction of framework or cradle, the method of securing the baffles when such are employed, and the manner of providing for the double seatings for the various fittings depending upon the type and construction of receptacle to which the invention is to be applied and the purpose for 4which it is to be emplyed.

, aving now described my invention what I claim as new and desire to secure by Letters Patent is Y 1. A tank for holding combustible liquids comprising a plurality of peripheral members, shaped in correspondencawith land adapted to fit in the tank, brace members holding the eripheral members in spaced relation, andp angularly related partitions carried by the peripheral members and'brace ange 'n upon such sleeve so as to form av members and formed with openings, and an inclosing shell bearing upon said peripheral members.

2. A tank for holding combustible liquids, comprising a plurality of spaced peripheral members formed of tubular material, the end *tween the horizontal partitions and connected therewith and with the vertical struts, a shell surrounding said members, ends engaging the end members and having flanges receiving the ends of the shell.

3. Atank for holding combustible liquids, comprising an internal skeleton cage having partitions and defining the size and shape of the tank, a metallic casing inclosing and bearing upon the cage vto reinforce said casing, and a rubber envelop closely fitting the casing.

4. A tank for holding combustible liquids, comprising an internal cage having peripheral members connected by struts to define the size and shape of the tank, a metallic casing overlying and bearing upon the peripheral members and struts to reinforce said casing, and a rubber envelop for the casing.
